Remove all remaining traces of JMangler (except from guide/features.html) & additional cleanup:
* remove stuff relating to the JMangler/JPLIS distinction
* reduce state in OTRE Transformations, we always have instances per class, now.
* cleanup logic to handle covariant return vs. super-delegating initial wrapper
* remove legacy LowerableTransformer (byte code compatibility not given anyway)
* remove legacy constructors in OTRE Transformations
